System for gravimetrically dosing bulk goods components having a transport container which can be coupled to and decoupled from a drive carriage

Abstract

The invention proposes a system for gravimetrically combining individual bulk material components in one or a plurality of transport container(s). The system comprises a plurality of storage containers for storing the bulk material components equipped with one dosing unit each in order to transfer a respective bulk material component into the transport container. Each of the storage containers is associated with a weighing means disposed below each storage container. The transport containers can be moved between the dosing units of the supply containers along a guidance and cooperate with the weighing means. In accordance with the invention, the guidance has several guiding segments that are disposed behind one another in the guiding direction and on which the transport container is guided, and at least the guiding segments disposed below the dosing units of the supply containers are formed by weighing/guiding segments which are mechanically decoupled from the other guiding segments or weighing/guiding segments such that the transport container is in its respective dosing position on the weighing/guiding segments for detecting its weight.

We claim: 
     
       1. A system for gravimetrically combining individual bulk material components in at least one transport container, the system comprising:
 a plurality of storage containers for storing the bulk material components; 
 a plurality of dosing units, each storage container cooperating with one dosing unit; 
 at least one transport container for accepting a respective bulk product component transferred by a dosing unit; 
 a plurality of weighing means, wherein each storage container is associated with one weighing means disposed below a respective storage container, said transport container being structured to cooperate with each of said weighing means; 
 a guidance along which said transport container can be moved between dosing units of said supply containers, said guidance having several guiding segments that are disposed behind one another in a guiding direction and on which said transport container is guided, wherein at least guiding segments disposed below said dosing units of said supply containers are formed by weighing/guiding segments, which are mechanically decoupled from other guiding segments and/or weighing/guiding segments, such that said transport container is in a respective dosing position on said weighing/guiding segments for detecting a transport container weight; and 
 at least one carriage, said carriage structured for displacing said transport container along said guidance, said carriage being driven in a controlled fashion, wherein said carriage is guided on a rail which extends parallel to said guidance, wherein said carriage can be coupled to and decoupled from said transport container by means of carriers. 
 
     
     
       2. The system of  claim 1 , wherein said weighing/guiding segments and said guiding segments are disposed in pairs, parallel to each other. 
     
     
       3. The system of  claim 1 , wherein said guiding segments and said weighing/guiding segments are formed by track sections, upper sides of which defining a guiding track for guiding means of said transport container. 
     
     
       4. The system of  claim 3 , wherein said guiding track of said track sections or said guiding means of said transport container are provided with rolling or sliding means. 
     
     
       5. The system of  claim 1 , wherein said carriage is guided on a rail. 
     
     
       6. The system of  claim 1 , wherein said carriage has at least two carriers, which are disposed at a separation from each other in said guiding direction and can be coupled to and be decoupled from said transport container. 
     
     
       7. The systems of  claim 1 , further comprising blocking means for said transport container for fixing said transport container in a respective dosing position. 
     
     
       8. The system of  claim 1 , wherein the system comprises several transport containers and several carriages. 
     
     
       9. The system of  claim 1 , wherein said transport container has a receiving opening which faces said dosing units of said supply containers and which can be closed, each of said closing units having a dosing opening which faces said transport container and which can be closed, wherein said receiving opening and said respective dosing opening can be moved to coincide during transfer of a respective bulk material component from a respective supply container into said transport container. 
     
     
       10. The system of  claim 9 , wherein said dosing opening of said dosing unit can be detachably connected to said receiving opening of said transport container in a substantially dust-free fashion, with said dosing unit thereby being mechanically decoupled from said transport container. 
     
     
       11. The system of  claim 10 , wherein said dosing opening of said dosing unit and/or said receiving opening of said transport container is/are disposed on said dosing unit or on said transport container by means of a resilient connecting element for preventing transfer of forces between said dosing unit and said transport container, wherein interconnected dosing/receiving openings can be arranged in a relative position with respect to said dosing unit or on said transport container such that transfer of forces between said dosing unit and said transport container is prevented by said resilient connecting element. 
     
     
       12. The system of  claim 11 , wherein said dosing opening and/or the receiving opening is/are arranged on a support which can be displaced substantially perpendicularly with respect to said dosing opening or substantially perpendicularly with respect to said receiving opening, said support being connected to said dosing unit and/or to said transport container via said resilient connecting element, wherein said support can be moved into a relative position with respect to said dosing unit or said transport container, wherein, in said relative position, said support is in contact with said dosing unit or said transport container exclusively via said resilient connecting element. 
     
     
       13. The system of  claim 9 , wherein a closure element of said dosing opening can be coupled to a closure element of said receiving opening and said closure elements can be displaced together between an open position and a closed position. 
     
     
       14. The system of  claim 1 , wherein said supply containers are arranged along said guidance in at least one row. 
     
     
       15. The system of  claim 1 , wherein said supply containers are arranged in at least two rows along at least two guidances, wherein said at least two guidances are associated with at least one relocating means, which is designed for relocating said transport container between said guidances. 
     
     
       16. The system of  claim 15 , wherein said relocating means is guided on rails or tracks, which extend substantially transversely to said guidances. 
     
     
       17. The system of  claim 15 , wherein said relocating means has at least one guiding segment, which can be aligned with said guiding segments and/or said weighing/guiding segments of said at least two guidances such that said transport container can be displaced between said guiding segments and/or said weighing/guiding segments of said at least two guidances and a guiding segment of said relocating means. 
     
     
       18. The system of  claim 1 , wherein said guidance is structured to be suspended.
